DEVICE FOR MANUFACTURING A CRYSTALLINE MATERIAL FROM A CRUCIBLE HAVING NON-UNIFORM HEAT RESISTANCE |
摘要 |
<p>The device forming a crucible for fabrication of crystalline material by directional solidification comprises a bottom and at least one side wall. The bottom presents a first portion having a first thermal resistance and a second portion having a second thermal resistance that is lower than the first thermal resistance. The second portion is designed to receive a seed for fabrication of the crystalline material. The bottom and side wall are at least partially formed by a tightly sealed part including at least one indentation participating in defining said first and second portions. The first portion is covered by a first anti-adherent layer having an additional first thermal resistance. The second portion may be covered by a second anti-adherent layer having an additional second thermal resistance that is lower than the first thermal resistance.</p> |
